The Rough Guide to Brain Training is a puzzle book which incluces essays and vignettes by myself. The book has 100 days of puzzles which will challenge your mental imagery, verbal fluency, numeracy, working memory and reasoning skills. There are puzzles that will look familiar like suduko, and some new ones I’ve never seen before. Fortunately the answers are included at the back. Gareth made these puzzles. I find them really hard.
I have 10 short essays in the book, covering topics such as evidence-based brain training, how music affects the developing brain, optimal brain nutrition and what the brains of the future will look like. As well as the essays, I wrote numerous short vignettes, helpful hints and suprising facts from the world of psychology and neuroscience (did you know that squids have dounut shaped brains? That you share 50% of your genes with a banana? That signals travel between brain cells at up to 200mph, which is fast compared to a cycle courier, but slow compared to a fibre optic cable). Throughout the book I try to tell it straight about what is, isn’t and might be true about brain training. I read the latest research and I hope I tell a sober, but optimistic, message about the potential for us to change how we think over our lifetimes (and the potential to protect our minds against cognitive decline in older age). I also used my research to provide a sprinkling of evidence-based advice for those who are trying to improve a skill, study for an exam or simply remember things better.
Writing the book was a great opportunity for me to dig into the research on brain training. It is a topic I’d always meant to investigate properly, but hadn’t gotten around to. The claims of those pushing commercial brain training products always seemed suspicious, but the general idea – that our brains change based on practice and experience – seemed plausible. In fact, this idea has been one of the major trends of the last fifty years of neuroscience research. It has been a big surprise to neuroscientists as experiment after experiment has shown exactly how malleable (aka ‘plastic’) the structure and function of the brain is. The resolution of this paradox of the general plausibility of brain training with my suspicion of specific products is in the vital issue of control groups. Although experience changes our brains, and although it is now beyond doubt that a physically and mentally active life can prevent cognitive decline across the lifespan, it isn’t at all clear what kinds of activities are necessary or essential for general mental sharpness. Sure, after practicing something you’ll get better at it. And doing something is better than doing nothing, but the crucial question is doing something you pay for better than doing something else that is free? The holy grail of brain training would be a simple task which you could practice (and copyright! and sell!!) and which would have benefits for all mental skills. Nobody has shown that such a task or set of tasks exists, so while you could buy a puzzle book, you could also go for a jog or go to the theatre with friends. Science wouldn’t be able to say for certain which activity would have the most benefits for your mental sharpness as an individual – although the smart money is probably on going jogging. It is to the credit of the editors at the Rough Guides that they let me say this in the introduction to the Rough Guide to Brain Training!
There wasn’t room in the book for all the references I used while writing it. This was a great sadness to me, since I believe that unless you include the references for a claim, you’re just spouting off, relying on a dubious authority, rather than really talking about science. So, to make up for this, and by way of an apology, I’ve put the references here. It will be harder to track specific claims from this general list that it would be with in-text citations, so if you do have a query, please get in touch and I promise will point you to the evidence for any claims I make in the book.
Additionally, I’ll be posting here a few things from the cutting room floor – text that I wrote for the book which didn’t make it into the final draft. Watch out, and if you do get your hands on a copy of this Rough Guide to Brain Training, get in touch and let me know what you think.
